The Cuviví is the only bird that inexplicably commits suicide. While most of the migrating human population in the Americas travels from south to north, the grassland bird flies in the opposite direction. Don Feliciano waits for the arrival of the animals once a year to harvest the carcasses on the immense beaches of the Ozogoche lagoons. Her granddaughter Sisa, a girl entering puberty dreaming of new opportunities, must decide whether her future will be in the community or away from it. While the indigenous Kichwa community waits for those who left to cross the USA-Mexico border, the birds' pilgrimage is welcomed to be eaten. Both Feliciano and his family struggle for the subsistence of their culture in the face of the threats of disappearing due to the temptations of the emigration phenomenon.
